...even as we promise ourselves to go to the gym three times a week!—a part of us knows we won’t do it. We are too old, or too clever, to give ourselves over fully to hope; we feel we must alloy it with resignation...
...MacGregor, a high-tech entrepreneur, runs NanoMuscle, an Antioch, Calif., company that makes 3-in. motors suitable for everything from power windows to dolls with nuanced facial expressions. "I like to be on the wave of the next insanely great thing," he says. His motors work because the alloy nitinol can assume different shapes as its temperature fluctuates. An electrical current causes a nitinol wire in the device to shorten, allowing the linear motor to contract like a human muscle but at 1,000 times the strength. That's a simple task but an important one, and one MacGregor believes...
...energy requirements in the first place. The steel that most cars are made of could be replaced by carbon-fiber polymers, which are lighter and more aerodynamic, as well as easy to make. The body panels on the diminutive Smart car from DaimlerChrysler are made of a recyclable thermoplastic alloy called Xenoy that is several times lighter than steel and helps the car get up to 65 m.p.g. Some 116,000 Smarts were sold last year in Europe and Japan, a 16% increase over 2000. But Americans' appetite for fast, powerful cars and roomy sport-utility vehicles (SUVs) makes...
Especially nowadays, I want results. Gold, silver or bronze. No tin, no plastic. None of that mystery alloy the government uses in those oddly light, play-money quarters it has been minting...
...President's ruling. An independent who voted for Bush, he would love to buy American, and until recently he did, sourcing his steel from a mill just 12 miles away. But that mill, owned by LTV, shut down last year. No other U.S. mill made the high-strength, low-alloy grade of steel that Sopko's client demanded. So Sopko started buying steel made in Europe by Arcelor and Corus...
